HARRY DE WALLACE, OF WATERTOWN, NEW YORK.

GEAR-CASE AND BRACKET.

SPECIFICATION forming part of Letters Patent No. 744,308, dated November17,1903. Original application filed May 16, 1901, Serial No. 60,543.Divided and this application filed February 24, 1902. Serial To all whomit may concern.-

Be it known that I, HARRY DE WALLACE, of Watertown, Jefferson county,NewYork,have invented certain new and useful Improvements in Gear-Cases andBrackets, of which the following is a specification.

This invention relates to improvements in gear-cases and bracketsdesigned particularly for use in connection with train-order signals andtrain-stopping devices of the class that are described and claimed inLetters Patent heretofore issued to me and numbered and dated asfollows: No. 617,232, dated January 3, 1899; No. 623,503, dated April18, 1899; No. 642,303, dated January 30, 1900; No. 657,592, datedSeptember 11, 1900, and also in my pending application for LettersPatent, filed May 16, 1901, Serial No. 60,543, of which this applicationis a division.

My present invention is designed to provide asimple and inexpensivebracket and gearcase that may be used between the truck .of thelocomotive and the train-order signal for the purpose of permitting theconnectingshaft to be set at any desired angle.

The invention consists generally in a bracket and gear-case, with ashaft mounted in hearings in the bracket'and with the gearcase mountedupon said shaft and capable of swinging thereon and furnishing bearingsfor another shaft, said casing also inclosing suitable gears forming aconnection between said shafts.

The invention consists, further, in the construotions and combinationshereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation of a locomotive embodying my invention. Fig. 2 isa section of the bracket and gear-case. Fig. 3 is another section takenon a plane at right angles to the plane of Fig. 2.

In the drawings, 2 represents a bracket of any suitable construction andhaving preferably a suitable base and two upright standards formingbearings for a shaft 3. The bracket 2 is secured upon any suitablesupport, preferably upon the frame of the locomotive, with the shaft 3parallel with the axles of the locomotive. I prefer to arrange the worm10 upon the shaft 3.

(No model.)

this bracket substantially over the forward axle 5 of the locomotive,and said axle is preferably provided with a pulley 6, and a belt 7(shown by dotted lines in Fig. 1) connects said pulley with the pulley 8upon the shaft 3. By this means the shaft 3 is-driven from the axle 5and in either direction as the locomotive runs forward or back. Asuitable casing 9 is mounted upon the shaft 3 between the standards ofthe bracket 2. Arranged upon the shaft 3 is a suitable wormgear 10,preferably secured in position by means of a pin 11. This pin ispreferably arranged opposite an opening in the casing that is closed bya threaded plug 12. By removing this plug the pin 11 can be removed andthe shaft 3 withdrawn, permitting the casing 9 to be removed from thebracket. One side of the casing 9 is preferably made removable, and itmay be secured in position by screws or other suitable means. A shaft 13is provided with bearings in the casing 9, said shaft extending at rightangles to the shaft 3. A worm-gear 14 is arranged upon the shaft 13within the casing 9 and-engages The casing 9 is made oil-tight and isprovided at its top with an opening having a threaded plug 15. Byremoving this plug the casing may be partially filled with oil, and thisoil lies at the bottom of the casing. The worm turning in this casinggathers up the oil, and as the worm revolves quite rapidly, even at amoderate speed of the locomotive, it throws the oil in every direction,thuslubricating all theworking parts and bearings perfectly. The shaft13 may extend in any direction from the casing 9, said casing beingadjustable around the shaft 3 to accommodate itself to the position ofthe shaft 13. As shown in Fig. 1 of the drawings, the shaft 13 extendson an incline from the casing 9 and is coupled to a shaft 17,t hat isinturn coupled to a shaft 18, leading to the train-order signal 19 in thecab of the locomotive. The pulley or sheave 8 is adjustable lengthwisefrom the shaft 3, so as to bring it directly over the pulley or sheave 6upon the locomotive-axle. The sheave 6 may be located inside or outsideof the wheel 20, and the sheave 8 will then be adjusted on the shaft 3to acroo commodate itself in position to the sheave 6. As the casing 9turns freely upon the shaft 3, it will be seen that the shaft 13 may bearranged horizontally, vertically, or in any intermediate position.

While I have shown and described this bracket and gear-casing asapplicable particularly to locomotives equipped with my train-ordersignal, I do not confine myself to its use in this particularconnection, as I believe that the same may be used to advantage for manyother purposes.

I claim as my invention and desire to secure by Letters Patent 1. Thecombination, with a suitable base plate or bracket, provided withsuitable standards, of a shaft mounted in said standards, a casingmounted upon said shaft, a gear upon said shaft within said casing, asecond shaft having bearings in said casings and a gear upon thesecond-named shaft engaging a gear upon the first-named shaft,substantially as described.

2. The combination, with a suitable base or bracket, provided withsuitable standards, of a shaft mounted in said standards, a casingmounted upon said shaft and capable of turning thereon, a worm upon saidshaft within said casing, a second shaft mounted in bearings in saidcasing and extending forward at right angles to first-named shaft andprovided with a gear or pinion engaging said worm, substantially asdescribed.

3. The combination, with the bracket, provided with suitable standards,of the shaft 3, mounted in said standards, the oil-tight casing 9arranged upon said shaft, the worm 10 arranged upon said shaft withinsaid casing, the shaft 13 mounted in hearings in said casing and thegear 14 mounted upon the shaft 13 and engaging in the worm 10,substantially as described.

In testimony whereof I have hereunto set my hand this 14th day ofFebruary, 1902.
